<p>Method for mfg. a tank with >=1 peripheral wall and two end plates is carried out by successively winding and impregnating with resin >=1 first mat strip of non-woven tangled fibres, a first strip of woven fibres or fabric with max. resistance in the weft direction, a second mat strip a second fabric strip with max. resistance in the warp direction and a third mat strip. Around the third mat strip is wound a sheet of adjacent tiles made of material with high resistance to compression in the direction of the thickness of the sheet. Two auxiliary mat layers are wound round successively, and finally a textile sheet is wound round the mat. The peripheral wall of the tank has high strength when subjected to external pressure.</p> |
